What is the author's style in Glory in Death by Nora Roberts?

The writer uses coarse, vulgar language in this book often, perhaps to bring home the flavor of the crimes, and the society it takes place in. Many of the characters in the book are police, exposed every day to what society has to offer. Vulgarity and sex abound, but the sex is not overly graphic. This novel is also peppered with technological terms, showing us that the world has made leaps and bounds technologically. However, many of the names assigned to things are fictional, and don't allude to the item the writer is trying to talk about.
